Cool refreshing type fabric performance test The choice of raw materials Choose five kinds of knitting fabric as to test the fabric, the fabric is from guangdong emerging group limited and hong xinglong cloth industry ltd collection, its various parameters as shown in table1.
Subjective and objective evaluation of fabric performance Objective and subjective evaluation method and its implementation process The subjective evaluation method is through the senses (touch, vision, hearing) to make specific evaluation of the degree of comfort and satisfaction and description in the physiology and the psychology to their feeling of clothing; objective evaluation method is to obtain the basic properties of clothing materials measured by instruments, including mechanical properties, Thermal and moisture and surface properties, transforming it into a certain index, to evaluate the material wearing comfort [2].

Preparation and Characterization of excellent flame retarded rigid polyurethane foams Anzhen Zhang a, Yihe Zhang＊b State Key Laboratory of Geological Processes & Mineral Resources, National Laboratory of Mineral Materials, School of Materials Science and Technology, China University of Geosciences (Beijing), Beijing 100083, China azaz1987@126.com,*bzyh@cugb.edu.cn Keywords: Rigid Polyurethane foam; Flame retardant; APP; EG; RP; DMMP; TCEP.
Polyurethane foam was the best performance of insulation materials, with low thermal conductivity, strong adhesion, and well water resistance. 49% of building insulation materials was the polyurethane foams materials in Europe and the United States, but there was less than 10% in China [1].
Experimental Materials.
This dilution was useful for the mixing of the raw materials and the foaming process, making a better foam structure.
